Re: [RE-wrenches] Ballasted Roof Racking Recommendations?

Hi Ryan, We have used the AET Rayport stainless steel ballasted racking system on dozens of installations and have been quite satisfied with the light ballast required (all open racking), integral module grounding, lightweight of materials (pressed stainless steel) and quickness of assembly.

Re: [RE-wrenches] Ballasted Roof Racking Recommendations?

Ryan, Panel Claw has a new product that mounts at 15 or 20 deg. but we have not used it yet. We do use the Grizzly Bear product, though and are very happy with it. I highly recommend it if you can utilize a 10 - 12 deg. tilt angle. [Description: NYLE LOGO SMALL] Mark Richardson Production Manager

Re: [RE-wrenches] Solmetric PVA and Tigo

I got an email from Solmetric on this question. Basically the optimizers change the way the modules look electrically so tracing the curve is not possible once optimizers are installed. They suggest tracing before or using the tool to pre-screen a client with shading issues to justify optimiz

Anyone have recommendations for a ballasted roof racking manufacturer?  Tilts of 30-degrees or more would be best.   Ryan HarkinsNABCEP Certified Solar PV Installer /Project Manager          PastedGraphic-3.pdf Description: Adobe PDF document Synergy Renewable Systems, LLCPO Box 58Stoughton, WI 53

Re: [RE-wrenches] Fronius replacement

JESSE: The Power-One specs lists 160V to 530V as the MPPT working range. It's possible to set the per MPPT input as low as 120VDC. Power-One does not provide info for loss of efficiency if the high-temp DC in[put voltage drops below 160V. Do you have any info on performance degradation betwe

Power One Inverters will easily string that low. We have used quite a few of these with no problem. They are ungrounded on the DC side. On Mon, Aug 27, 2012 at 3:22 PM, Jesse Dahl wrote: > I think some Solectria inverters have a low number (115vdc). The > Solectrias I have worked with had a ma

Re: [RE-wrenches] Ilsco SGB bonding lug

The WEEB-LUG is great for rail bonding: http://www.we-llc.com/grounding-lug.html It is UL467, marked Outdoor Use, made of tin-plated copper. The only disadvantage is that the stainless steel clip must be sacrificed if the lug is moved - a disadvantage of all WEEB grounding products. Jason Szumlan
